Abstract
Escherichia coil heat-labile enterotoxin (LT) and cholera toxin (CT) w ere found to inhibit intracellular antigen processing. Processing was not inhibited by mutant LT with attenuated ADP-ribosyltransferase acti vity, CT B or LT B subunit, which enhanced presentation of preexisting cell surface peptide-class II major histocompatibility complex comple xes. Inhibition of antigen processing correlated with A subunit ADP-ri bosyltransferase activity.
